Rainbow Heroes Legend

Three hundred years ago, troubled times came. The Taizu of the Xia Dynasty held the divine sword "Tian Yuan" and fought against all the heroes in the world. Finally, he fought the sword master of the "Rainbow Demon" in the wilderness. In the end, the Taizu of the Xia Dynasty defeated the sword master of the "Rainbow Demon", unified the world, and founded the Xia Dynasty. At this time, "Tian Yuan" and "Rainbow Demon" disappeared at the same time. Although there were occasional disturbances in the world, it was generally peaceful and entered a peaceful age. Now, a young man carrying a long sword stepped into the world. Since then, waves have appeared frequently, and a heroic legend belonging to them has begun.
